Russia steps up attack on Azovstal plant with people still trapped inside

Russian forces on Tuesday resumed an assault on the Azovstal steel plant, thought to be the last bastion of a Ukrainian regiment in the besieged city of Mariupol, after civilians were evacuated from the area. Ukrainian fighters announced that Russian forces began storming the facility, which includes a warren of underground tunnels and bunkers. It came as a convoy carrying dozens of civilians evacuated from the plant over the weekend arrived in the relative safety of Ukrainian-controlled Zaporizhzhia.
